Hi all, this patch provides an implementation of xc_map_foreign_bulk for minios. In order to do so it modifies map_frames_ex and do_map_frames to take an int *err as parameter and return any error that way.

Hi Xen folks! I''ve faced with one strange thing in ARM version of Xen: when I use xc_map_foreign_bulk() to map some memory from domU to dom0, after unmap() for previous returned address - memory is not freed at all. Let''s look at call stack: xc_map_foreign() -> linux_privcmd_map_foreign_bulk() -> { addr = mmap(fd); ioctl(fd, IOCTL_PRIVCMD_MMAPBATCH_V2 ); } ->...

Hi all, when running Windows 2008 SBS on Xen 4.0.0, it disappears after some time (longest time I had it running was 20 minutes). In /var/log/xen/qemu-dm-win1.log I find: xc_map_foreign_batch: mmap failed: Cannot allocate memory xc_map_foreign_bulk error 12 Anyone any idea how to troubleshoot this? The Hypervisor has 16 GB of RAM, currently 2 GB are allocated to Dom0. This specific DomU has 8 GB. thx, B. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-us...

This is a cherry pick of two patches that add support for guest paged out frames in the XCP 2.6.32 dom0 patch queue. First patch propagates the ENOENT returned by the hypervisor in the case of a paged out page, all the way up the call chain to the MMAPBATCH_V2 ioctl. The ioctl is mainly used to harvest those return values and retry. The second patch adds retry loops to all backend grant

We created a 64bit SLES11 SP1 guest, and then used a script to change memory (using mem-set command) periodically (in 1 second): set 1G, set 2G, set 1G, set 2G, and so on. After a few minutes, we encountered QEMU exit due to SIGBUS error. Below is the call trace captured by gdb: The call trace: Program received signal SIGBUS, Bus error. 0x00007f94f74773d7 in memcpy () from /lib64/libc.so.6 (gdb)

Hi all, this is the long awaited patch series to add xen device model support in qemu; the main author is Anthony Perard. Developing this series we tried to come up with the cleanest possible solution from the qemu point of view, limiting the amount of changes to common code as much as possible. The end result still requires a couple of hooks in piix_pci but overall the impact should be very
